Eclipse has some problem re-running single JUnit tests if
the tests are in Junit 3 format, but the JUnit 4 launcher
is used. This was quite unnecessary and the move was not
completed. We still have no JUnit4 test.

This completes the extermination of JUnit3. Most of the
work was global searce/replace using regular expression,
followed by numerous invocarions of quick-fix and organize
imports and verification that we had the same number of
tests before and after.

- Annotations were introduced.
- All references to JUnit3 classes removed
- Half-good replacement for getting the test name. This was
  needed to make the TestRngs work. The initialization of
  TestRngs was also made lazily since we can not longer find
  out the test name in runtime in the @Before methods.
- Renamed test classes to end with Test, with the exception
  of TestTranslateBundle, which fails from Maven
- Moved JGitTestUtil to the junit support bundle

java.io.File.delete() reports failure as an exceptional
return value false. Fix the code which silently ignored
this exceptional return value. Also remove some duplicate
deletion helper methods.

indexState() encodes the complete state of the index
into one readable String. This helps to write tests
against the index. indexState() is enhanced to optionally
also contain the content of the files in the index.

The new Add command adds files to the Git Index. 
It  uses the DirCache to access the git index. It 
works also in case of an existing conflict. 

Fileglobs (e.g. *.c) are not yet supported. 

The new Add command does add ignored files because
there is no gitignore support in jgit yet.
